MODELING AND DIAGNOSTICS OF THE RESEARCHER’S SYNERGIC INTERACTION WITH THE SCIENTIFIC COMMUNITY
05.13.10 Management in social and economic systems
DescriptionThe article presents innovative models and methods to diagnose the researcher’s synergic interaction with the scientific community (social mega-environment). It is known that the researcher’s interaction with the social mega-environment has two main directions: scientific collaboration and using the scientific community’s social and cultural potential; the former appears as scientific publications, while the latter appears as scientific citations. It is also known that synergic interaction is the interaction leading to the increase in activity results (according to the “1+1>2” scheme). In the article, the researcher’s synergic interaction is understood as his/her collaboration-based research activity that leads to obtaining the results impossible without this interaction. The theoretical significance of the research results is in the possibility for the further development of the sociology of science, as well as for the further development of the models of the individual’s interaction with the social environment; the practical significance is in the possibility to analyze the factors contributing to the success in the research activity of academic researchers and research teams (i.e. applicable for monitoring the research activity)

05.13.10 Management in social and economic systems
DescriptionThe article considers the most used methods and means of knowledge extraction taking into account the quality assessment of models in decision support systems. In scientific and practical terms, the possibilities of joint effective use of expert systems, data mining (IAD) and machine logical inference (MLV), which provides deeper data processing, taking into account the significant differences between databases (DB) and knowledge bases (BZ). DB is a unit of information unrelated to each other information, while BZ – not only related to each other, but also with the concepts of the world, which makes it possible to solve complex multi-criteria problems in various subject areas. Currently, increasing attention is paid to non-network technologies that have the ability to simulate nonlinear processes, work with noisy data, as well as the ability to learn and self-study, extracting essential features from the incoming information. At the same time, the integration of neural network technologies and artificial intelligence models into a single hybrid system together with the methods of logical inference in the form of a hierarchical sequence of the "If-then" rules structure significantly improves the understanding of the studied process and the quality of presentation of the result. Nevertheless, these methods and means of knowledge extraction are insufficient if the fuzzy linguistic inference mechanism is not used. The basic characteristic of fuzzy sets is the membership function, which is a generalized characteristic of a normal set. To set this feature, we use three types of shapes – triangular, trapezoidal and Gaussian type and two main procedures – phasefication and de-phaseification which is considered by the example of the method of Mamdani. Along with the stated most promising direction in this area is the adaptive gain algorithm called AdaBoost, where the limitation of the gain due to the filtering is to apply the subsampling circuit which has the normal contour of batch training, reusable training data. This provides an opportunity to work with weak models, and in the conditions of hybridization causes efficiency increase, strengthens the classifiers united in the "Committee". Each next set of classifiers is built on objects incorrectly classified by previous sets. AdaBoost is sensitive to data noise and emissions and is less susceptible to retraining, which can significantly reduce the number of examples and obtain better output in the DSS

05.13.10 Management in social and economic systems
DescriptionThe article deals with the complexity of the construction of engineering theories in both scientific and practical direction based on the use of non-traditional approach to the problems of effective data monitoring, especially in the field of control systems of multicomponent representation of objects of system analysis. The study of the complexity of this issue involves a detailed consideration of the relationships of the elements of these objects on the basis of known methods, while the integration of heterogeneous knowledge obtained by such often independent methods becomes very time-consuming and poorly formalized. Currently, the processing of information and its subsequent presentation have changed significantly through the use of data mining (IAD), which includes not only the organization of the knowledge system in various missile defense, but also in the field of DSS. This, in turn, contributes to the effective formalization of fuzzy information and processing it in the form of fuzzy algorithms, which is an extension of the decision support system based on fuzzy logic – DSS NL. At the same time, it is necessary to emphasize the features of the proposed approach of the DSS NL, which is that it can be used in various missile defense systems, including for the effective analysis of statistical information of multicomponent representation of objects, which is used in determining statistical indicators to identify and assess existing and potential risks, adverse situations, as well as in the preparation of motivational grounds for managerial decision-making. For the purpose of more detailed establishment in real missile defense of the relations between objects it is offered to carry out by means of various degrees of dependence. For example, the types of graded connections are considered as fuzzy objective connections, and the use of expert systems and semantic links led to the construction of hypotheses analysis of situations and semantic relationship between them. A significant difference of the considered DSS NL is that each model is formed on the basis of a separate semantic network, and the system itself works with several models of Pro related or unrelated to each other. On the basis of the use of the concept of the relationship of proximity between concepts, belonging to the situation, its information part of the recommendations Are grouped according to the selected situation for their subsequent analysis and decision-making. On the basis of the principle of coordinating actions and construction of the function, taking into account the optimal time of the control action, the General algorithm of decision support for emergency production situations in the Pro low-rise construction, both in urban and rural areas

05.13.18 Mathematical modeling, numerical methods and software complexes
DescriptionThe research purpose is identification and justification of the scientific team’s recognition citation-based criteria. Such parameters of the educational environment as modality, latitude, social activity, social coherence, intensity, maturity etc. are assessable on the basis of the primary information about the scientific team’s research activity results. The authors of this article prove that the data about cross-citations within a scientific team is the primary information about the scientific and pedagogical team members’ recognition of their social system (such information is obtainable from modern scientometric databases, e.g. Russian Science Citation Index). The new scientific results of this research are the identified citation-based criteria for the scientific team’s recognition. The theoretical significance of these results is the possibility of using them as a scientific basis for further research in the sociology of science and for the development of the small social systems functioning models; the practical significance is the possibility to analyze the factors for the success of scientific and pedagogical teams’ research activity (i.e. applicability for the research activity monitoring systems). The research methods are: the methods of set, relations and graph theory, the methods of qualimetry, mathematical statistics (including the scree-plot method) and linear. The research methodology is based on the sociological approach (viewing the scientific and pedagogical team as a well-established social system), the qualimetric approach (declaring the necessity for the multicriterial diagnostics of scientific and pedagogical team’s recognition) and the probabilistic and statistical approach (viewing the scientific and pedagogical team’s recognition citation-based diagnostics as a statistic measurement)

METHODOLOGY OF OPTIMAL PLACEMENT OF TRADE NETWORK OBJECTS
05.13.18 Mathematical modeling, numerical methods and software complexes
DescriptionThe article outlines the idea of a methodology for locating distribution centers of a spatially distributed distribution network without restrictions on the territory. In the past fifteen years in Russia, the profitability of offices and retail space has been significantly higher than logistic complexes. At present, it is possible to talk about a change in the investment attractiveness of the segment of distribution centers and storage facilities. The method consists in solving three problems: determining the number of distribution centers that need to be placed using the method of comparing options; determination of the best locations for placement of distribution centers using the ant colony algorithm; identification of the best location from the previously determined ant colony algorithm using the penalty function method. This method of optimal placement of objects of a spatially distributed complex can be applied not only to the distribution network, but also to any transport company with distribution centers, for example, a logistics company, delivery services, etc.

Description
In the conditions of the Northern and Southern foothill zones of the Krasnodar Territory, the soil preparation Reasil® Soil conditioner was tested to study its effect on the water – physical properties and structural state of the chernozem of ordinary and alluvial meadow soils. Field and field experiments were conducted in the Northern Zone when maize was cultivated in irrigation. The preparation was applied before sowing by the spreader "Amazone" under pre-sowing cultivation (to a depth of 12 cm) at a dose of 400 kg / ha. In the South foothill zone, the experiment was conducted on a crop – a seedling tomato. The preparation was applied before planting seedlings in a dose of 200 kg / ha. It was established that the application of meliorant did not significantly change the density and total porosity in the arable and subsoil layers of alluvial meadow soil, which was 1,46–1,47 g / cm3 and 44,3–44,5 %, respectively, with practically no pores occupied air (porosity of aeration). However, the use of ameliorant on this soil contributed to an increase in the content of agronomically valuable aggregates in the arable and subsoil horizons, respectively, by 15,9 and 22 %, and the sum of waterproof aggregates by 8,4 and 1,5 %. In the northern zone, when maize was grown, it was established that the application of meliorant did not significantly change the soil density and total porosity in the arable and subsoil layers of the chernozem plain, where it amounted to 1,29–1,32 g/cm3 and 51,6–51,5 % at rather high aeration porosity. The meliorative method reduced the content of agronomically valuable aggregates in the arable layer of chernozem by 15,4 % and increased their quantity in the subsoil horizon (1,4 %). The number of waterproof aggregates increased on the variant with the use of ameliorant, respectively, by 19,9 and 2,8 %

RESTORATION OF A MODEL OF A DYNAMIC NONLINEAR SYSTEM FROM THE TIME SERIES GENERATED BY IT
DescriptionThe main task in the analysis of time series is the reconstruction of the dynamical system that generated this series. To illustrate the nature of the behavior of a dynamic system described by a nonstationary time series, a «phase portrait» method is proposed. An acceptable description of the phase space of a dynamical system can be obtained if we take instead of real variables of the system delay vectors composed of the values of the series at consecutive moments of time. Restoration in a given class of a system of differential or difference equations is performed based on the scalar time series of the observed process. In order to eliminate the measurement error and accurately represent the position of the object in the current, future, or any of the past moments, it is proposed to apply the Kalman filter using the known mathematical model of object dynamics

THE IMPLEMENTATION OF THE CONCEPT OF "ELECTRONIC GOVERNMENT" IN HIGHER EDUCATION
DescriptionIn the article, based on the generalization of long-term operation of archives of Kuban state University, we present current regulations and practice of work with archival documents, pressing questions of transition to paperless acquisition, storage and use of documentary resources of the organization. The author conducted a detailed analysis of the functioning of the archives of the University taking into account the specifics of the focus of the organization, defined the main tasks of the archive. The role of the archive is considered in the context of source of historical and cultural heritage of society. We highlighted problems of control and storage of archival documents, due to the steady growth of documentary information. Due to the rapid development of electronic document management today, the approach to the management of archival documents is formed based on electronic technologies. Based on the analysis and the identified problems, the article presented constructive proposals for the introduction of an electronic document archive organization if the interaction with the EDMS and other systems. To speed up the process of working with paper media, we might use the technology of digitization. It is obvious that now, without implementation of modern information technologies it is impossible to organize effective accounting, storage and use of archival documents
